I agree that she's an unmistakable ENFP. But as a few have said, he does seem somewhat INTP to me. It's easy to think F because it's a romantic movie, but INTPs fall in love and become vulnerable and feel hurt, too. To me, the giveaway is how uncomfortable this makes him and how he tries to escape when it goes awry.

It's possible. I didn't pay much attention, just skipped around, and my judgment was based on his general portrayal in the movie, but it's a romantic movie so it's expected there's going to be a lot of feelings & values motivating everything. Might have to watch it again in full and look for repeated clues

I completely agree on her being ENFP...he seemed more ISTx to me though. Just seemed pretty practical-minded (though maybe just in comparison to her...) I didn't get anything that said "N" about him, though to be fair he doesn't say all that much, and there's other types I could see him being...INTJ, INFJ, etc.

edit: something that just occurred to me, I've noticed that a lot of times people identify main characters/likeable characters with their own type. Maybe the best-written characters have traits that many people can identify with.

I think you may be right about people identifying main characters with themselves and their own type. Now that I think about it, I don't remember any specific evidence for him being N or S. Maybe I just superimposed an N impression on him. I could relate to how quiet and awkward he was, and how he didn't know what to say to her except "You seem nice." He seemed a little too accommodating in that "first" conversation to be a T. But that's weak evidence for F; Ts can be polite too. Edit: She seemed a lot more rude and seemed to run roughshod over him, which seems a little odd if she were an EF and he an IT, but that could have just been a function of her Extroversion. I question whether she was necessarily F; to me, she could easily have been T.

It's also completely possible that he straddled some fences with regard to N/S, T/F, and whatever else. Especially as people age, I think they straddle fences more and more.

They're running just like you
For you, and I, wooo
So people, people, need some good ol' love
